AMAZEAN JUNGLE THAILAND BY UTMB

THA Betong , THA | 30 Apr - May 3, 2026

Deep in southern Thailand's rainforest, where ancient jungle trails and misty mountains await at the edge of civilization.

AMAZEAN JUNGLE THAILAND BY UTMB plunges runners into the dense tropical rainforest of southern Thailand near Betong. This race offers a raw jungle experience with steep muddy trails, river crossings, and lush vegetation beneath a canopy alive with wildlife.

In the deep south of Thailand, near the Malaysian border, the AMAZEAN JUNGLE THAILAND BY UTMB takes trail running to its most primal form. The course winds through dense tropical rainforest around Betong, one of the most biodiverse regions in Southeast Asia. Runners navigate slippery root covered trails, ford streams and climb through mist shrouded mountains where the jungle canopy filters the light into an emerald glow.

This is not a manicured trail race. The terrain is raw, steep and unpredictable, with mud, humidity and tropical heat creating conditions that test both physical fitness and mental resilience. The reward is total immersion in a landscape of staggering natural beauty, where gibbons call from the treetops and exotic birds flash through the undergrowth.

As one of the most unique stops on the UTMB World Series, AMAZEAN JUNGLE THAILAND offers an adventure that is impossible to replicate anywhere else. The warmth of Thai hospitality, the flavors of southern Thai cuisine and the thrill of running through untouched jungle make this a race that redefines what trail running can be.
